A) Put the following events associated with fertilization in thecorrect order.
- binding of ZP3 receptors in sperm to ZP3
- formation of zygote
- acrosome reaction
- release of intracellular Ca2+ in the ovum
- resumption of meiosis
B) What effect would blocking intracellular calcium release haveon an ovum immediately after fertilization?
*Select one or more:*
a. Meiosis II would not occur
b. The sperm would not release phospholipase C-zeta into thecytoplasm
c. MPF levels would not decrease
d. Cortical granules would not be released
C) List all the differences that exist in the control of sexualmotivation or sex drive in female rodents and primates. Choose ALLcorrect answers.
a. Female rodents only engage in sexual behavior around the timeof ovulation whereas female primates engage in sexual behaviorthroughout their reproductive cycles.
b. Sexual motivation in female primates is less dependent onhormones released by their ovaries than is sexual behavior infemale rodents.
c. Blocking estrogen synthesis around the time of ovulationwould decrease sexual motivation in female primates but not inrodents.
d. Sexual behavior in female rodents is dependent on beingexposed to estradiol and then 48 hours later to testosterone, whilesex drive in female primates is increased by being exposed first toestradiol and then 48 hours later to progesterone.
